La tutela penale ambientale e la nozione di rifiuto fra istanze soprannazionali ed approdi nostrani

Lotta alla criminalita' e salvaguardia dei diritti e delle liberta' fondamentali nell'U.E.

La ricerca è dedicata a verificare se e come, a livello dell’Unione europea, la lotta alla criminalità (ed in particolare quella organizzata) venga condotta nel rispetto di diritti e libertà fondamentali, e se la cooperazione tra Stati membri su questo fronte possa giungere a promuovere standard omogenei ed elevati di tutela degli stessi. Gli ambiti di cooperazione interessati sono principalmente quello giudiziario in materia penale e quello di polizia, e la ritrosia degli Stati a cedere all’Unione competenze in materia si è accompagnata ad un ritardo ancora maggiore dell’emersione, nell’ambito degli stessi, della dimensione dei diritti. Ciò ha reso molto difficile lo sviluppo completo ed equilibrato di uno “spazio di libertà, sicurezza e giustizia” (art. 67 TFUE). L’assetto istituzionale introdotto dal Trattato di Lisbona e l’attribuzione di valore giuridico vincolante alla Carta hanno però posto le basi per il superamento della condizione precedente, anche grazie al fatto che, negli ambiti richiamati, la salvaguardia dei diritti è divenuta competenza ed obiettivo esplicito dell’Unione. Centrale è per la ricerca la cooperazione giudiziaria in materia penale, che ha visto la ricca produzione normativa di stampo repressivo recentemente bilanciata da interventi del legislatore europeo a finalità garantista e promozionale. L’analisi degli strumenti nella prospettiva indicata all’inizio dell’esposizione è quindi oggetto della prima parte dell’elaborato. La seconda parte affronta invece la cooperazione di polizia e quello degli interventi volti alla confisca dei beni e ad impedire il riciclaggio, misure – queste ultime - di particolare rilievo soprattutto per il contrasto al crimine organizzato. Sottesi all’azione dell’Unione in queste materie sono, in modo preponderante, due diritti: quello alla salvaguardia dei dati personali e quello al rispetto della proprietà privata. Questi, anche in ragione delle peculiarità che li caratterizzano e della loro natura di diritti non assoluti, sono analizzati con particolare attenzione.

La cooperazione giudiziaria in rete nello spazio di liberta', sicurezza e giustizia

L’oggetto del lavoro si concentra sull’analisi in chiave giuridica del modello di cooperazione in rete tra le autorità nazionali degli Stati membri nel quadro dello Spazio LSG, allo scopo di valutarne il contributo, le prospettive e il potenziale. La trattazione si suddivide in due parti, precedute da una breve premessa teorica incentrata sull’analisi della nozione di rete e la sua valenza giuridica. La prima parte ricostruisce il percorso di maturazione della cooperazione in rete, dando risalto tanto ai fattori di ordine congiunturale quanto ai fattori giuridici e d’ordine strutturale che sono alla base del processo di retificazione dei settori giustizia e sicurezza. In particolare, vengono elaborati taluni rilievi critici, concernenti l’operatività degli strumenti giuridici che attuano il principio di mutuo riconoscimento e di quelli che danno applicazione al principio di disponibilità delle informazioni. Ciò allo scopo di evidenziare gli ostacoli che, di frequente, impediscono il buon esito delle procedure di cooperazione e di comprendere le potenzialità e le criticità derivanti dall’utilizzo della rete rispetto alla concreta applicazione di tali procedure. La seconda parte si focalizza sull’analisi delle principali reti attive in materia di giustizia e sicurezza, con particolare attenzione ai rispettivi meccanismi di funzionamento. La trattazione si suddivide in due distinte sezioni che si concentrano sulle a) reti che operano a supporto dell’applicazione delle procedure di assistenza giudiziaria e degli strumenti di mutuo riconoscimento e sulle b) reti che operano nel settore della cooperazione informativa e agevolano lo scambio di informazioni operative e tecniche nelle azioni di prevenzione e lotta alla criminalità - specialmente nel settore della protezione dell’economia lecita. La trattazione si conclude con la ricostruzione delle caratteristiche di un modello di rete europea e del ruolo che questo esercita rispetto all’esercizio delle competenze dell’Unione Europea in materia di giustizia e sicurezza.

"Orationi al cepo overo a la scala": le laude della Confraternita bolognese di S. Maria della morte

La Confraternita bolognese di S. Maria della Morte, istituita nel 1336 sull’onda della predicazione del frate domenicano Venturino da Bergamo, è la più antica e meglio documentata compagnia italiana ‘di giustizia’. Possedeva un laudario conosciuto attraverso 12 manoscritti redatti tra XV e XVI secolo, dove le laude seguono il “confortatorio” che insegnava ai confratelli come relazionarsi col condannato e prepararlo a morire in perfetto spirito cristiano. Nelle laude l’identificazione poetica tra Cristo e il condannato era funzionale allo scopo di convertire il criminale in santo, convincendolo che la sua morte aveva una funzione redentrice per sé e la città stessa. L’assoluzione plenaria poteva essere ottenuta solo tramite una morte completamente accettata e un pentimento sincero. La dissertazione indaga le tematiche espresse dalle laude e le motivazioni forti che spingevano i confortatori a intraprendere questa peculiare attività assistenziale.

La prova penale nelle indagini difensive. Analisi comparata degli strumenti processuali concessi alla difesa nei sistemi italiano e statunitense.

L’elaborato si occupa di fare il punto in materia di indagini difensive a tre lustri dall’entrata in vigore della legge n. 397/2000, epilogo di un lungo processo evolutivo che ha visto da un lato, una gestazione faticosa e travagliata, dall’altro, un prodotto normativo accolto dagli operatori in un contesto di scetticismo generale. In un panorama normativo e giurisprudenziale in continua evoluzione, i paradigmi dettati dagli artt. 24 e 111 della Costituzione, in tema di diritto alla difesa e di formazione della prova penale secondo il principio del contraddittorio tra le parti, in condizioni di parità, richiedono che il sistema giustizia offra sia all’indagato che all’imputato sufficienti strumenti difensivi. Tenuto conto delle diversità che caratterizzano naturalmente i ruoli dell’accusa e della difesa che impongono asimmetrie genetiche inevitabili, l’obiettivo della ricerca consiste nella disamina degli strumenti idonei a garantire il diritto alla prova della difesa in ogni stato e grado del procedimento, nel tentativo di realizzare compiutamente il principio di parità accusa - difesa nel processo penale. La ricerca si dipana attraverso tre direttrici: l’analisi dello statuto sulle investigazioni difensive nella sua evoluzione storica sino ai giorni nostri, lo studio della prova penale nel sistema americano e, infine, in alcune considerazioni finali espresse in chiave comparatistica. Le suggestioni proposte sono caratterizzate da un denominatore comune, ovvero dal presupposto che per contraddire è necessario conoscere e che solo per tale via sia possibile, finalmente, riconoscere il diritto di difendersi indagando.

Reservoir characterization of the Cardium Formation in the Ferrier Oilfield, west-central Alberta, Canada.

This thesis has the main aim of defining the lithostratigraphy, depositional architecture, post-depositional modifications and reservoir characteristics of the Cardium Formation in the Ferrier Oilfield, and how these characteristics can have great impact over production rates, GOR and produced fluid discrimination. In the Ferrier area, the Cardium Formation is composed by a NE prograding clastic sequence made up of offshore to shoreface deposits sealed by marine shales. The main reservoir is composed by sandstones and conglomerates interpreted to have deposited in a shoreface depositional environment. Lithofacies and net reservoir thickness mapping led to more detailed understanding of the 3D reservoir architecture, and cross-sections shed light on the Cardium depositional architecture and post-deposition sediment erosion in the Ferrier area. Detailed core logging, thin section, SEM and CL analyses were used to study the mineralogy, texture and pore characterization of the Cardium reservoir, and three main compartments have been identified based on production data and reservoir characteristics. Finally, two situations showing odd production behaviour of the Cardium were resolved. This shed light on the effect of structural features and reservoir quality and thickness over hydrocarbon migration pathways. The Ferrier example offers a unique case of fluid discrimination in clastic reservoirs due both to depositional and post-depositional factors, and could be used as analogue for similar situations in the Western Canadian Sedimentary Basin.

How Porous are the Walls that Separate Us?: Transformative Service-Learning, Women’s Incarceration, and the Unsettled Self

In this article, we refine a politics of thinking from the margins by exploring a pedagogical model that advances transformative notions of service learning as social justice teaching. Drawing on a recent course we taught involving both incarcerated women and traditional college students, we contend that when communication among differentiated and stratified parties occurs, one possible result is not just a view of the other but also a transformation of the self and other. More specifically, we suggest that an engaged feminist praxis of teaching incarcerated women together with college students helps illuminate the porous nature of fixed markers that purport to reveal our identities (e.g., race and gender), to emplace our bodies (e.g., within institutions, prison gates, and walls), and to specify our locations (e.g., cultural, geographic, socialeconomic). One crucial theoretical insight our work makes clear is that the model of social justice teaching to which we aspired necessitates re-conceptualizing ourselves as students and professors whose subjectivities are necessarily relational and emergent.

The Effects of Prenatal Exposure to Altered Melatonin Levels on Hippocampal Gene Expression in the Male Rat

The stability of the circadian rhythm for mammals depends on the levels of serotonin and melatonin, neurohormones that signal for lightness and darkness, respectively. Disruption in the stability of neurohormones has been shown to be a critical factor in psychopathological disorders in humans. For example, altering levels of melatonin in utero through administration of melatonin or the melatonin receptor antagonist, luzindole, has been shown to cause changes in developmental growth and adult behavior in the male rat. Analysis of relative adult hippocampal gene expression with RT-PCR revealed differences in ARNTL expression that suggested abnormality in clock gene expression of the rats that were prenatally exposed to altered levels of melatonin. Differences in the degree of plasticity as suggested by previous behavior testing did not result in differences in gene expression for GABA receptors or NMDA receptors. Morevoer, growth associated protein 43, GAP-43, a protein that is necessary for neuronal growth cones as well as long term learning has been found to be critical for axon and presynaptic terminal formation and retention in other studies, but hippocampal gene expression in our study showed no significant alteration after exposure to various maternal melatonin levels. However, ARNTL is a key regulatory component of clock genes and the circadian cycle so that alterations in the expression of thi critical gene may lead to critical changes in neuronal growth and plasticity. Our data support the conclusion that the manipulation of maternal melatonin levels alters the brain development and the circadian cycles that may lead to physiological and behavioral abnormalities in adult offspring.

Creatine and neurotrophin-4/5 promote survival of nitric oxide synthase-expressing interneurons in striatal cultures

Nitric oxide (NO) mediates a variety of physiological functions in the central nervous system and acts as an important developmental regulator. Striatal interneurons expressing neuronal nitric oxide synthase (nNOS) have been described to be relatively spared from the progressive cell loss in Huntington's disease (HD). We have recently shown that creatine, which supports the phosphagen energy system, induces the differentiation of GABAergic cells in cultured striatal tissue. Moreover, neurotrophin-4/5 (NT-4/5) has been found to promote the survival and differentiation of cultured striatal neurons. In the present study, we assessed the effects of creatine and NT-4/5 on nNOS-immunoreactive (-ir) neurons of E14 rat ganglionic eminences grown for 1 week in culture. Chronic administration of creatine [5mM], NT-4/5 [10ng/ml], or a combination of both factors significantly increased numbers of nNOS-ir neurons. NT-4/5 exposure also robustly increased levels of nNOS protein. Interestingly, only NT-4/5 and combined treatment significantly increased general viability but no effects were seen for creatine supplementation alone. In addition, NT-4/5 and combined treatment resulted in a significant larger soma size and number of primary neurites of nNOS-ir neurons while creatine administration alone exerted no effects. Double-immunolabeling studies revealed that all nNOS-ir cells co-localized with GABA. In summary, our findings suggest that creatine and NT-4/5 affect differentiation and/or survival of striatal nNOS-ir GABAergic interneurons. These findings provide novel insights into the biology of developing striatal neurons and highlight the potential of both creatine and NT-4/5 as therapeutics for HD.

Marked elevation in cortical urate and xanthine oxidoreductase activity in experimental bacterial meningitis

Experimental bacterial meningitis due to Streptococcus pneumoniae in infant rats was associated with a time-dependent increase in CSF and cortical urate that was approximately 30-fold elevated at 22 h after infection compared to baseline. This increase was mirrored by a 20-fold rise in cortical xanthine oxidoreductase activity. The relative proportion of the oxidant-producing xanthine oxidase to total activity did not increase, however. Blood plasma levels of urate also increased during infection, but part of this was as a consequence of dehydration, as reflected by elevated ascorbate concentrations in the plasma. Administration of the radical scavenger alpha-phenyl-tert-butyl nitrone, previously shown to be neuroprotective in the present model, did not significantly affect either xanthine dehydrogenase or xanthine oxidase activity, and increased even further cortical accumulation of urate. Treatment with the xanthine oxidoreductase inhibitor allopurinol inhibited CSF urate levels earlier than those in blood plasma, supporting the notion that urate was produced within the brain. However, this treatment did not prevent the loss of ascorbate and reduced glutathione in the cortex and CSF. Together with data from the literature, the results strongly suggest that xanthine oxidase is not a major cause of oxidative stress in bacterial meningitis and that urate formation due to induction of xanthine oxidoreductase in the brain may in fact represent a protective response.

Silencing of microRNAs in vivo with 'antagomirs'

MicroRNAs (miRNAs) are an abundant class of non-coding RNAs that are believed to be important in many biological processes through regulation of gene expression. The precise molecular function of miRNAs in mammals is largely unknown and a better understanding will require loss-of-function studies in vivo. Here we show that a novel class of chemically engineered oligonucleotides, termed 'antagomirs', are efficient and specific silencers of endogenous miRNAs in mice. Intravenous administration of antagomirs against miR-16, miR-122, miR-192 and miR-194 resulted in a marked reduction of corresponding miRNA levels in liver, lung, kidney, heart, intestine, fat, skin, bone marrow, muscle, ovaries and adrenals. The silencing of endogenous miRNAs by this novel method is specific, efficient and long-lasting. The biological significance of silencing miRNAs with the use of antagomirs was studied for miR-122, an abundant liver-specific miRNA. Gene expression and bioinformatic analysis of messenger RNA from antagomir-treated animals revealed that the 3' untranslated regions of upregulated genes are strongly enriched in miR-122 recognition motifs, whereas downregulated genes are depleted in these motifs. Analysis of the functional annotation of downregulated genes specifically predicted that cholesterol biosynthesis genes would be affected by miR-122, and plasma cholesterol measurements showed reduced levels in antagomir-122-treated mice. Our findings show that antagomirs are powerful tools to silence specific miRNAs in vivo and may represent a therapeutic strategy for silencing miRNAs in disease.

Oral melatonin reduces blood coagulation activity: a placebo-controlled study in healthy young men

Melatonin has previously been suggested to affect hemostatic function but studies on the issue are scant. We hypothesized that, in humans, oral administration of melatonin is associated with decreased plasma levels of procoagulant hemostatic measures compared with placebo medication and that plasma melatonin concentration shows an inverse association with procoagulant measures. Forty-six healthy men (mean age 25 +/- 4 yr) were randomized, single-blinded, to either 3 mg of oral melatonin (n = 25) or placebo medication (n = 21). One hour thereafter, levels of melatonin, fibrinogen, and D-dimer as well as activities of coagulation factor VII (FVII:C) and VIII (FVIII:C) were measured in plasma. Multivariate analysis of covariance and regression analysis controlled for age, body mass index, mean arterial blood pressure, heart rate, and norepinephrine plasma level. Subjects on melatonin had significantly lower mean levels of FVIII:C (81%, 95% CI 71-92 versus 103%, 95% CI 90-119; P = 0.018) and of fibrinogen (1.92 g/L, 95% CI 1.76-2.08 versus 2.26 g/L, 95% CI 2.09-2.43; P = 0.007) than those on placebo explaining 14 and 17% of the respective variance. In all subjects, increased plasma melatonin concentration independently predicted lower levels of FVIII:C (P = 0.037) and fibrinogen (P = 0.022) explaining 9 and 11% of the respective variance. Melatonin medication and plasma concentration were not significantly associated with FVII:C and D-dimer levels. A single dose of oral melatonin was associated with lower plasma levels of procoagulant factors 60 min later. There might be a dose-response relationship between the plasma concentration of melatonin and coagulation activity.
